What is the design procedure of mechanical parts urgently ah?!
5. assembly and parts diagram design. According to the structure and size of parts assembly sketches to determine the complete assembly and parts diagram design. (according to the plan to determine the main dimensions, structure design, parts drawing, sorting out the map) four, as the case with technical documentation requirements, design and coding machine calculation manual, manual, standard parts list, purchased parts list, etc. in the conditions of acceptance in the design process, such as a link the problem is feasible or not, need to return to revise the previous design, until the problem is solved. Sometimes, for this reason, even the whole project has to be knocked over. Therefore, the mechanical design process is an iterative process. (standard and outsourcing parts arrangement, specification preparation, acceptance documents
The technical design includes the following work: 1. kinematic design. According to the design scheme and the working parameters of the working mechanism, the dynamic parameters of the prime mover, such as power and speed, are determined, and the size and movement parameters of each component are determined. 2. dynamics calculation. According to the result of kinematic design, the load acting on the part is calculated. 3. part design. According to the load and design criterion of parts, the basic dimensions of parts are determined by means of calculation, analogy or model test. 4. overall assembly draft design. According to the basic dimensions of the components and the structure of the mechanism, the overall assembly sketch is designed. On the basis of considering the assembly, adjustment, lubrication and processing technology of parts, the structure and dimension design of all parts are completed. Determine the parts of the structure, size and parts of the relationship between the location, you can accurately calculate the role of the load on the parts, analysis of factors affecting the work capacity of parts, such as stress concentration. On this basis, the main parts should be checked and calculated, such as accurate calculation of shaft strength, life calculation of bearings. According to the result of calculation, the structure and size of parts can be modified repeatedly until the design requirements are met.
